IBQTTLEJFQ-R SIIPPLYING LIQUIDS IN DROPS.-

Application filed September 25, 1924. Serial No. 739,806.

To all whom it may concern:

Be it known that I, JULES KRAENTZEL, a subject of the King of the Belgians, residing at Brussels, Belgium, 38 Boulevard Maurice Lemonnier, have invented new and useful Improvements in Bottles for Supplying Liquids in Drops, of which the following is a specification.

The present invention relates to an improved type of bottle for supplying in the form of drops liquids such as dentifrices, medicines and perfumes.

An embodiment of: the invention is, by way of example only, illustrated by the accompanying drawing, wherein:

Fig. 1 is a an elevation of a complete bottle according to the invention;

Fig. 2 is a section of the device controlling the admission of air and the passage of the liquid, and

Fig. 3 is a front elevation of a cap formin a part of the said device.

Tteferring to the said drawing, it will be seen that the bottle offers the peculiarity of being bell-shaped or flared towards the base, whereby an easy grip and an increased stability are obtained.

The body 1 of the bottle is made of glass or other suitable ceramic material; the head of the said bottle has twoopposed outwardly projecting end-portions of which one 2 is closed and rounded, while the other 3 is open and cylindrical. The latter is fitted with a device for controlling the admission of air into the bottle and the passage of the liquid, the said device including a metal cap 4 provided with two holes 5 and 6 situated symmetrically respectively above andbelow the centre of the cap 4. An air admission tube 7 extends horizontally within the head from the upper hole 5 towards the rounded end-portion 2 of the said head. In this lastnamed portion of the head is placed a cork plug 8 into which the free end of the tube 7 penetrates and which is pierced so as to atford a passage of suitable diameter for the air roundthe end of the said tube 7 The lower hole 6 serves to allow the passage of the liquid, and both holes may be closed simultaneously bv means of two stoppers of rubber, or other suit-able material, carried by a bridge piece 9 secured on a pivot-pin 10 extending through the centre of the cap 4 and provided at its outer end with a serrated operating knob 10. The other end adjusting the action of the spring 11.

of the said pin has secured thereon a washer 11 against which bears one end of a spring 11 which is coiled round the pin 10 and bears at its other end against the inner face of the cap 4. The washer 11 may be replaced by a cotter-pin or the like, but when a Washer is used, it may be threaded so as to be capable of engaging a threaded portion of the pivot pin 10 for the purpose of The portion of the pivot-pin 10 projecting within the cap 4, the washer 11 and the spring 11 are enclosed in a dished casing hermetically fixed to the said cap 4.

It will be readily understood that if the operating knob 10 is pulled against the action of the spring 11 and rotated so as to place the two stoppers with their common axis crosswise in relation to the common axis of the two holes 5 and 6, and if the bottle is then suitably inclined, the liquid contained therein will be supplied drop by drop through the hole 6 while air is admitted via the hole 5 and the tube 7. When no liquid is required, the action of the spring 11 automatically keeps the two stoppers applied on the holes 5 and 6, thus preventing evaporation and leakage of the liquid.

To fill the bottle, the cap 4 and the parts carried thereby are removed.

It is to be observed that owing to the provision of the projecting rounded end-portion 2 of the head of the bottle, any possibility of the liquid obstructing the air admission tube is avoided.

I claim:

In an improved bottle for supplying liquids in drops, the combination with a bottle having a bell-shaped body and a head with two opposed outwardly projecting end-portions of which the first, fitted inside with a I pierced cork plug, is closed and rounded while the second is open and cylindrical, of

metal .oap fitted on said cylindrical por- I tion of the head and provided with a hole for the admission of air and a hole for the passage of liquid situated symmetrically re-- spectively above and below the centre of said cap, and air admission tube extending within the head of the bottle from the firstnamed hole towards the rounded end-porpin, aseat for one end of said spring on the In testimony whereof I signed hereunto inner end of sand pivot pm, and a bridge my name in the presence of two subscribing piece secured on the outer portion or said Witnesses.
